Always in the oven or on stove top except for the dutch oven. Ready for duty! Mine is treasured and used almost daily.
My best skillet belonged to my mom and dad originally, that is at least 50 years old and still a treasured tool at our home. Wooden utensils are best. My dutch oven is at least 40 years old, and will be used this weekend at a chili cook off. One of my sister's is from our grandmother's kitchen and we remember it being used at family gatherings in the early 1960's.
Use it often, and treat it right and it will last a life time and then for future generations.
Basic steps for care and use are easy.
Season it with oil when first used, clean it after each and every use, (hand wash NO soap, bristle brush or salt as abrasive), re-season it with a dab of oil after cleaning, never let it stay wet for more than 2 minutes and make sure it is bone dry when storing
I hand wash with NO soap ever, use a little water to boil off any residue, or deglaze and then rinse with clear water, heat on low to dry. Re-season with a dab of oil and then cool before placing in storage.
Can't beat it for cornbread, cobbler, beans, chicken, gumbo, jambalaya, and the list goes on and on.
Best of luck!
